In part because of this community involvement, Spurs fans have been among the most loyal in the NBA. The Spurs set several NBA attendance records while playing at the Alamodome, including the largest crowd ever for a NBA Finals game in 1999, and the Spurs continue to sell out the smaller, more intimate AT&T Center on a regular basis. The Spurs' rallying cry of "Go Spurs Go!" has endeared itself to the city of San Antonio, and the phrase pops up all over the city as the season progresses into the playoffs and the Spurs inch closer to a possible title.

San Antonio has also garnered praise for the way its citizens celebrate Spurs championships. When the Spurs win a title, San Antonians jam up the streets downtown, march around waving flags, throw confetti and honk car horns until dawn, but with little incidence of crime. There has yet to be a major riot involving a Spurs title celebration.

After missing the playoffs for the first time in their existence in 1972-1973, the team was put up for sale. The team was acquired by a group of 36 San Antonio businessmen, led by Angelo Drossos and Red McCombs who actually leased the team from the original Dallas ownership group, relocated the team to San Antonio, Texas and renamed them the Spurs. The team's primary colors were changed from the red, white, and blue of the Chapparrals to the now familiar silver and black motif of the Spurs.

The team quickly made themselves at home at San Antonio's HemisFair Arena playing to increasingly large and raucous crowds. The early Spurs were led by ABA veteran James Silas and bolstered by the acquisition in early-1974 of future NBA Hall-of-Famer George Gervin from the Virginia Squires. Even though playoff success would elude the team in the ABA, the Spurs had suddenly found themselves among the top teams in the ABA. In 1976, the ABA folded, threatening the future of San Antonio's sole professional sports franchise. The NBA however decided to admit four ABA teams into the league, with the Spurs being one of them along with the Denver Nuggets, Indiana Pacers and the New York Nets.

Although there was some initial skepticism in league circles regarding the potential success and talent levels of the incoming ABA teams, the Spurs would prove worthy of NBA inclusion during the 1975-1976 season with a record of 44-38, good for a tie for fourth place overall in the Eastern Conference. The Spurs would go on to capture 5 division titles in their first 7 years in the NBA and became a perennial playoff participant.

The decade of the 1980s marked both highs, then lows, and an eventual high. For the first few seasons of the decade, the Spurs continued their success of the 1970s with records of 52-30 in 1980-1981, 48-34 in 1981-1982, and 53-29 in 1982-1983. Despite their regular season success, the Spurs were unable to win any NBA championships, losing in the Western Conference playoffs to the Houston Rockets in 1981 and the Los Angeles Lakers in 1982 and 1983.

After the 1984-1985 season, Gervin, who arguably had been the Spurs' biggest star, was traded to the Chicago Bulls in what effectively signaled the end of the era that began when the Spurs first moved to San Antonio.

The next four seasons were a dark time in Spurs' history, with the team having a combined record of 115-215 from 1985-1986 until 1988-1989. The losing seasons and dwindling attendance often caused the Spurs to be mentioned as a potential candidate for relocation to another city. The lone bright spot during this period was the Spurs' being awarded the top pick in the 1987 NBA draft through NBA Draft Lottery. The Spurs used this selection on United States Naval Academy standout David Robinson. Although drafted in 1987, the Spurs would have to wait until the 1989-1990 season to see Robinson actually play due to a two-year commitment he had to serve with the United States Navy.

Although the 1988-1989 season was the worst in Spurs history at 21-61, it was notable for several reasons. It was the first season of full ownership for Red McCombs, who was an original investor in the team and helped solidify local ownership for the team. Additionally, the 1988-1989 season featured the debut of Larry Brown as the Spurs head coach who moved to San Antonio after winning the NCAA National Championship with the University of Kansas in 1988.

As the 1980s ended, the 1989-1990 season proved to be the rebirth of the Spurs franchise. Led by Robinson along with the newly added Terry Cummings and 1989 draftee Sean Elliott, the Spurs achieved the biggest one-season turnaround in NBA History, finishing with a record of 56-26. The Spurs eventually lost in the Western Conference semifinals after losing a seven-game series to the eventual Western Conference champion Portland Trail Blazers. Robinson had one of the most successful rookie seasons for a center in NBA history, finishing the season as Rookie of the Year while averaging 24.3 points and 12.0 rebounds.

The Spurs began the 1990s with great optimism. The team became a perennial playoff presence although were never able to advance further than the second round of the NBA Playoffs under Brown's tutelage. Late in the 1991-1992 season, McCombs fired Brown and replaced him with Bob Bass who finished the season as interim head coach. McCombs made national headlines during the summer of 1992 with the hiring of former UNLV head coach Jerry Tarkanian. The Tarkanian experiment proved a flop, as the coach was fired 20 games into the 1992-1993 season with the Spurs record at 9-11. After Rex Hughes filled the coaching shoes for one game, NBA veteran John Lucas was named head coach. It was Lucas's first NBA coaching assignment although he had gained recognition in league circles for his success in helping NBA players rehab from drug abuse.

The Lucas era started out successfully. His coaching propelled the team to a 39-22 finish over the rest of the regular season and the team reached the Western Conference semifinals, losing to the Phoenix Suns. The 1992-1993 season also marked the last that the Spurs would play in HemisFair Arena. In 1993 local businessman Peter M. Holt and a group of 22 investors purchased the Spurs from Red McCombs for $75 million.

The following season, the Spurs first in the newly built Alamodome, Lucas led the Spurs to a 55-27 record but the team suffered a loss in the first round of the playoffs to the Utah Jazz which led to the immediate firing of Lucas as head coach. Prior to the season the Spurs traded fan-favorite Elliott to the Detroit Pistons in return for rebounding star Dennis Rodman.

Lucas was replaced by former Pacers coach Bob Hill for the 1994-1995 season which would turn out to be the Spurs' most successful until 2006. Elliott returned to the team after an uneventful season with the Pistons and the team finished with the best record at 62-20 while David Robinson was named the NBA's Most Valuable Player. The Spurs reached the Western Conference Finals, but lost to the eventual NBA Champion Houston Rockets. Throughout the season and particularly in the playoffs there appeared to be friction developing between Rodman and several Spurs' teammates, most notably Robinson, and Rodman was traded after the season to the Chicago Bulls.

The Spurs finished the next season (1995-1996) under Hill at 59-23 and lost in the Western Conference Semifinals to the Jazz. Few observers could have predicted how far the Spurs would fall during the 1996-1997 season. After an injury that limited Robinson to six games during the season, the Spurs wound up with a 20-62 record, the worst in franchise history. Hill only lasted 18 games that season, eventually being replaced by Gregg Popovich, who had once been an assistant for the Spurs during Larry Brown's coaching turn.

Although the 1996-1997 season was not successful on the court for the Spurs, the offseason proved to be the opposite. With the third-worst record in the league, the Spurs won the NBA's draft lottery which gave them the top pick in the 1997 draft. The Spurs used their pick to select Wake Forest University product and consensus All-American Tim Duncan.

Duncan quickly emerged as a force in the NBA during the 1997-1998 season, averaging 21.1 points and 11.9 rebounds per game as a power forward. He was named First Team All-NBA while winning Rookie of the Year honors. The team ended up at 56-26 but once again lost to the Jazz in the Western Conference semifinals. While both Duncan and Robinson played low-post roles, the two seamlessly meshed on the court.

Playing a shortened 50-game season, the Spurs ended up with a 37-13 record. The team was just as dominant in the playoffs, rolling through the Western Conference with a record of 11-1. They faced the New York Knicks in the NBA Finals and, on June 25, 1999, won the series and the franchise's first NBA Championship in Game 5 (final score: 78-77) on the Knicks' home court of Madison Square Garden. Duncan was named the Finals MVP. The victory by the Spurs was not only the first NBA title to be won by a former ABA team, but also was the first Finals appearance by a team from the ABA.

The Spurs were not able to capitalize on their success during the 1999-2000 season. Although they finished with an overall record of 53-29, the Spurs lost in the first round to the Suns primarily due to an injury to Duncan which kept him out of the playoff series. The longterm viability of the Spurs franchise in San Antonio was however achieved during the 1999-2000 season, as Bexar County voters approved increases on car rental and hotel taxes which would allow for the construction of a new arena near Freeman Coliseum.

The Spurs finished with 58-24 records for both the 2000-2001 and 2001-2002 seasons but found themselves suffering playoff ousters in both seasons from the eventual NBA Champion Los Angeles Lakers.

Prior to the 2002-2003 season, the team revealed their new logo, dumping the "fiesta colors" which had become unpopular with fans. Entering the 2002-2003 season, the team knew it would be memorable for at least two reasons, as David Robinson announced that it would be his last in the NBA and the Spurs would begin play at their new arena (approved in 1999 by County voters), the SBC Center (now the AT&T Center), named after telecommunications giant SBC, whose corporate headquarters are located in San Antonio. This version of the Spurs was very different from the team that had won the title a few years earlier. The Spurs had remade their team in an attempt to dethrone the three-time defending NBA Champion Los Angeles Lakers. Second-year French star Tony Parker was now the starting point guard for the Spurs and the squad featured a variety of three-point shooters including Stephen Jackson, Danny Ferry, Bruce Bowen, Steve Kerr, Steve Smith and Argentina product Manu Ginobili. Mixing the inside presences of Duncan and Robinson with the newer outside threats, the Spurs earned a 60-22 record. In the playoffs, the Spurs defeated the Suns, Lakers and Dallas Mavericks en route to facing the New Jersey Nets in the NBA Finals. The series against the Nets marked the first time two former ABA teams would play each other for the NBA Championship. The Spurs won the series 4-2, giving them their second NBA Championship in franchise history. Duncan was named both the NBA Regular Season and Finals MVP for the season.

In the 2003-2004 season, the Spurs were knocked out of the playoffs by the Lakers in the Western Conference Semifinals. The Lakers rallied from a 0-2 hole in the series and won 4 straight. The series was defined by a controversial game-winning shot in Game 5 by Derek Fisher with 0:00.4 left in the game. After the stunning loss, the Spurs traveled to Los Angeles for Game 6, where they lost the game and the series. The Spurs spent the following offseason tweaking the team.

In the 2005-2006 season, the Spurs broke their franchise record for wins in a season (63-19) and qualified for the playoffs for the ninth year in a row. (The Spurs and Indiana Pacers currently share the NBA's longest active consecutive playoff appearance streak with nine in a row — see Active NBA playoff appearance streaks.) However, the defending-champion Spurs were eliminated in the second round by the Dallas Mavericks in a 7-game semifinal series that, due to a quirk in the playoff ranking system, featured the two top teams in the conference.

The Spurs look poised to contend for several titles to come. The three key players (Duncan, Ginobili, Parker) are under contract until at least 2009. The Spurs had hoped to buy out the contract of Ginobili's countryman Luis Scola, a power forward whom the Spurs had drafted in 2002; however, it appears that the Spurs are looking to trade the rights to Scola even though the asking price of TAU Cerámica is down to $3.5 million, keeping the possibility open that they could still pursue him.

The Spurs have been uncommonly successful among NBA teams in finding foreign talent as demonstrated by selecting Manu Ginobili ( 20px1999 NBA Draft 57th pick) and Tony Parker ( 20px2001 NBA Draft 29th pick) who have both become All Stars. The Spurs own the NBA rights to the players listed in the table below. The typical pattern is to allow the player to develop in leagues outside the USA. The player is free to negotiate contracts in other leagues and is not obligated to play in the NBA.
